.. cfgcmd:: set system option kernel amd-pstate-driver <mode>
Enables and configures p-state driver for modern AMD Ryzen and Epyc CPUs.
The available modes are:
* ``active`` This is the low-level firmware control mode based on the profile
set and the system governor has no effect.
* ``passive`` The driver allows the system governor to manage CPU frequency
while providing available performance states.
* ``guided`` The driver allows to set desired performance levels and the firmware
selects a performance level in this range and fitting to the current workload.
This will add the following two options to the Kernel commandline:
* ``initcall_blacklist=acpi_cpufreq_init`` Disable default ACPI CPU frequency scale
* ``amd_pstate={mode}`` Sets the p-state mode
.. note:: Setting will only become active with the next reboot!
.. seealso:: https://docs.kernel.org/admin-guide/pm/amd-pstate.html
.. cfgcmd:: set system option kernel quiet
Suppress most kernel messages during boot. This is useful for systems with
embedded serial console interfaces to speed up the boot process.
